Product Brief
Description
Features
The AFBR-811VxyZ Twelve Channel, Pluggable, Parallel
Fiber Optics Transmitter and AFBR-821VxyZ Twelve
Channel, Pluggable, Parallel Fiber Optics Receiver are high
performance fiber optics modules for short-range parallel
multi-lane data communication and interconnect applications. The high density optical modules are designed to
operate over multimode fiber systems using a nominal
wavelength of 850 nm.
• Compliant to IEEE 802.3ba 100GbE (100GBASE-SR10
and nPPI) per lane
Avago’s MiniPOD solution offers system designers two
module package options to optimize their cable management and board layout. AFBR-811RxyZ Tx/AFBR-821RxyZ
Rx is used with round multi-lane cable assemblies for
applications requiring multiple turns of the jumper cable
inside the chassis. AFBR-811FxyZ Tx/AFBR-821FxyZ Rx is
used with flat ribbon cable assemblies, allowing dense
tiling of the modules as the jumper cables can be thread
under the dust-cap of the next module. This top mounted
optical connection maximizes board layout density by
eliminating board space lost to the optical connector and
strain relief.
• High density footprint: 21.95 mm × 18.62 mm size
The electrical interface uses a 9×9 MEG-Array connector
with 1.27 mm pitch

The optical interface requires the user to provide a
custom designed optical turn 1×12 ribbon cable PRIZM
LightTurn connector.
The thermal interface provided can require either a user
provided heat sink or use of the Avago general purpose
clip on heat sink, to maintain the module case temperature
to be between 0 °C to 70 °C during continuous operation.

Laser Safety Notice
* A Class 3R laser is considered safe if handled carefully, with restricted beam viewing.
With a class 3R laser the maximum permissible exposure can be exceeded, but with
a low risk of injury.
